TRENTON, N.J. (CBS) — Proponents of a measure that would expand the use of medical marijuana in New Jersey are putting pressure on governor Chris Christie to approve a plan that passed the legislature last month (see related story).

Today, more than 2,000 letters were delivered to Christie’s office on behalf of Vivian Wilson, a two-year old girl from North Jersey who suffers from a rare form of epilepsy that can only be relieved by ingesting marijuana.

Her mom, Meghan Wilson, is hoping the state will relax restrictions on the quality of the cannabis grown and the number of doctors required to sign off on a child’s prescription.

“We’re hoping (Gov. Christie) realizes that his opinion is really in the minority,” Wilson said today. “People want Vivian and other children to have access to these strains of marijuana.”

Christie has another week to decide on the legislation; his office says he is reviewing the bill.

The governor has steadfastly insisted on strict controls on medical marijuana in the name of public safety. Should Christie veto the bill, the Wilsons say they will move to Colorado, where the laws are not as strict.
